Backtrace of X's segfault
Misread, and forgot I had used inline rects for SNA as well. Master should have had the segfault fixed already. commit afdb8aa89a88c62ccd5e26a3ed9adb70fec310a8 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Sep 7 20:10:02 2011 +0100 sna/gen3: Do not assume video updates are always vsync'ed In case the video is running async, then there may be subsequent instructions within the batch and so we do need to mark the clobbered state as dirty when setting up the video frame.

Created attachment 50962 [details] i915_error_state from debugfs after the GPU has hung Hi When I use Xv as the video output for mplayer (command line "-vo xv"), the GPU immediately hangs. This only happens with xf86-video-intel from git and SNA enabled. Using Xv with UXA works fine (with DDX from git and 2.15). dmesg says the GPU is hung: [ 237.939989] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 237.939999] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [ 237.941102] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 11893 at 11892, next 11894) Afterwards, when I start mplayer with Xv output again after the GPU hung the way I described above, X segfaults. My card is 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) and the kernel version is 3.0 (have not tested any other).
